Original question:

[TDA4VM] SERDES_REFCLK

Hello,

I have see the question of [TDA4VM] Treatment for SERDES_REFCLK, the PCIE_REFCLKx and SERDES4_REFCLK can be define to input or output,

1. If we only using SERDES0 for SGMII and SERDES4 for display port, the PCIE_REFCLKx and SERDES4_REFCLK can be floating or connector to GND?

2. If we don't using SERDES1~3 port, TI suggest these pin need floating or connector to GND?

Best regards,

Tony
